Heaviest stellar black hole discovered in nearby galaxy

Astronomers have located an exceptionally massive black hole in orbit around a huge companion star. By combining data from NASA's Chandra X-ray Observatory and the Gemini telescope on Mauna Kea, Hawaii, M33 X-7 was determined to be the most massive stellar black hole known. This result has intriguing implications for the evolution and ultimate fate of massive stars.

1. New type of massive stellar death
   12-20-2006 · EurekAlert!
   So far we have thought that the signature of the death of a massive star was an energetic explosion called a "supernova." New observations show that this is not always the case. On the contrary, a team led by Danish researchers has now discovered that some massive stars die by collapsing into a black hole returning very little material into the interstellar medium. The new discovery is published in Nature.

2. New X-ray source in nearby galaxy spawns mystery
   01-09-2008 · EurekAlert!
   Astronomers studying a nearby galaxy have spied a rare type of star system -- one that contains a black hole that suddenly began glowing brightly with X-rays. Though this type of star system is supposed to be rare, it's the second such system discovered in that galaxy, called Centaurus A. The discovery suggests that astronomers have more to learn about the lives and deaths of massive stars in galaxies such as our own.

3. RIT study predicts how fast a black hole can be booted from a galaxy
   05-30-2007 · EurekAlert!
   Scientists at RIT have discovered for the first time just how fast a supermassive black hole can be thrown from a galaxy when it merges with another black hole. The crucial factor in producing large "kicks" turns out to be the spin that the black holes carry prior to the merger.Manuela Campanelli and her team derived a formula that for the first time predicts the size and direction of the kick, or radiation recoil.

4. Unusual supernovae may reveal intermediate-mass black holes in globular clusters
   01-29-2008 · EurekAlert!
   A strange and violent fate awaits a white dwarf star that wanders too close to a moderately massive black hole. According to a new study, the black hole's gravitational pull on the white dwarf would cause tidal forces sufficient to disrupt the stellar remnant and reignite nuclear burning in it, giving rise to a supernova explosion with an unusual appearance.

5. Largest, brightest supernova ever seen may be long-sought pair-instability supernova
   05-07-2007 · EurekAlert!
   UC Berkeley astronomers Nathan Smith and David Pooley report the most luminous supernova ever detected, the explosion of a super-massive star in a galaxy 250 million light years away. The scientists estimate the star was 150 times larger than our sun, and that it exploded via an entirely new mechanism never before observed. Unlike other massive supernovas, this so-called pair instability supernova left behind no black hole.

6. Scientists reveal how supermassive black holes bind into pairs during galaxy mergers
   06-07-2007 · EurekAlert!
   Now, using supercomputers to simulate galaxy mergers, scientists at Stanford and elsewhere have seen the formation of a new type of structure-a central disk of gas that can be from a hundred to a few thousand light years wide and from a few hundred million to a billion solar masses. They report the first simulated formation of a supermassive black hole (SMBH) pair in the June 7 edition of Science Express, an online version of Science magazine.

   Supermassive black holes have been discovered to grow more rapidly in young galaxy clusters, according to new results from NASA's Chandra X-ray Observatory. These "fast-track" supermassive black holes can have a big influence on the galaxies and clusters that they live in.

8. Astronomers discover new kind of black-hole explosion
   12-20-2006 · EurekAlert!
   Scientists have discovered what appears to be a new kind of cosmic explosion -- a "hybrid gamma-ray burst" -- which will be the subject of four articles to be published in the journal Nature on 21 December 2006. The scientists include four astrophysicists at Penn State University as well as others around the globe. The nature of the explosion is a puzzle in "virtually uncharted territory" for space scientists.

9. A brother for the Milky Way's black hole
   07-25-2007 · EurekAlert!
   Is a second black hole lurking at the heart of the Milky Way? We know there is one colossal black hole at the centre of the galaxy, but so far no one has managed to verify the existence of a second. Now, an astrophysicist at the University if California says a simple test could answer the question. Look for a pair of hypervelocity stars hurtling out from the centre of the galaxy at breakneck speed.

10. Mystery cosmic explosions
    12-20-2006 · EurekAlert!
    Scientists have discovered what appears to be a new kind of cosmic explosion, the subject of four articles in this week's issue of Nature. They call the explosion a hybrid gamma-ray burst.As with other gamma-ray bursts, this hybrid burst is likely signalling the birth of a new black hole. It is unclear, however, what kind of object or objects exploded or merged to create the black hole or, perhaps, something even more bizarre.
